Avid BB7 MTB G2 Front or Rear Rotor

I got one of these about a year ago to replace a cheap brake on a campus bike, and liked it so much that I got another one for my mountain bike build. These brakes are easy to maintain, requiring only a couple tools to completely overhaul it, let alone keep it running. I do notice that these brakes are noisy when they get wet, but otherwise are very quiet. The stopping power is great, and I feel I can go faster safely because I can rely on these brakes to stop me quickly. I have not used hydros, but when coupled with the speed levers from Avid, these have a lot of modulation. Installation is easy, and getting the rotors to not rub is simple. All the screws have thread locking material on them, and I have yet to worry about a screw coming loose. The set comes with all the hardware you need to mount to the front or the back, minus cables and housing. Once the pads start to wear down, it's just a simple matter of a click every few months to keep the pad clearance right. The only gripes I have with them is the rubber boot that wears out, but these could honestly run without them, and the noise when wet, which comes with the territory of disc brakes. These do take a bit to wear in, but once you get it, these brakes perform very well. I doubt that I will be using others in future builds.

It took me about 1 1/2 hours to install both brakes including fine adjustments (1 hr. on the first one, 2nd went much quicker. This also included removing the old ProMax or "zoom" brakes). The boxes came with everything I needed for complete installation on front and rear. My bike is a Mongoose XR-PRO 29", which came with horrible disk brakes. After installation I took a 5 1/2 mile ride around the hilly back streets of Ashland, KY. I was very surprised and impressed at the stopping power of these brakes compared to my stock brakes! Absolutely no comparison. And they are very smooth and quiet. I haven't experienced any squealing noises yet. Maybe I will later, but on this initial test run they were as quiet and smooth as can be. The price of these brakes is very reasonable, and THEY DO COME WITH PADS, in case you are not sure. The adjustment "knobs" for both inside and outside pads make adjusting these brakes very easy and precise. I realize I've only used these for a short ride, but if they continue to be as great as this, they couldn't be any better.

Bought my wife a new specialized Myka and myself a new kona splice. Was not happy with the stock tektro brakes. Figured they needed adjusting and such. But to me the brakes are important because we want to haul a kiddy trailer behind us for our future kids. Wanted the extra braking power to ensure ours and our kids safety if that we were going down hills or motorists not watching. Took 30 min per brake. Or a hour per bike for removing old brakes and installing the new brakes with proper adjustment. Was quite easy. I'm slightly mechanically inclined but haven't done much work on bikes before. Used the stock adapter on the specialized myka for the rear brake. Performance wise, before break in fronts would now be able to throw me over and can perform stoppies with pretty good control. They are noisy and sound awful, they are supposed to quiet down after break in. Rear brakes don't have the noise that the fronts do. Must be something to do with the way they are mounted. Much greater stopping power over the tektro. I now have the ability to lock up the rear brakes where as I could not do that before. I'd buy them again. A must upgrade in my books. And much cheaper then going to hydraulic brakes.

If I had not found the TRP's, these would get 4 stars. They lock up really easily. Still way better than rim brakes and cheap for how well they work, but TRP's are like anti-lock brakes and these are like the brakes on my '89 Camaro. They stop pretty well, but make me nervous on big tech descents and when I'm out of the saddle on steep stuff.

Lets face it, if you can't trust your brakes, you're never going to push the limits on your bike. That may not be your thing, but confidence is even more important if you just ride occasionally for a little exercise. Avid BB7's are all about quality and simplicity. Easy adjustment, lots of reliable stopping power. Not the lightest brakes in the world, but you have to make trade off's somewhere.

I've upgraded the brakes on my hard-tail MTB from the stock OEM brakes to these and am super satisfied with these brakes. They are generally smoother and have excellent stopping power. No doubt these are some of the best mechanical disc brakes you can buy. Are they better than much more expensive (like XTR kinda expensive) hydraulic brakes? No. They are much better than any hydraulic brake, including some of Avids, at this price-point and they do compare well to many hydraulic brakes, having similar braking power and modulation (paired with SD7 levers). But if you're looking into these you probably already understand the pros and cons of hydraulic brakes and mechanical brakes, so I'm going to say I definitely recommend this if you're looking for a pair of kick ass mechanical disc brakes. One helpful thing I can tell you, look up how to install these, ignoring any suggestions to buy super expensive brake cables. Taking the extra two minutes to learn how will help you get these dialed in much easier. You may also want to sand the rotors a bit to help the pads bed in quicker.

The BB7 disc brake caliper always works. I have never had a bad one or any installation problems. The BB7 is an excellent value for the money. I quit using pinch brakes and went to disc brakes long ago. Rotor size choices help control your braking. I use a 180 disc on the front and a 160 on the back. Road bikes should consider reversing this number, using the larger 180 discs on the back. Many riders can avoid using the 180 on the front and instead use the 160 on the back and front.

I got these to replace the Elixir 3 hydraulic brakes that came on my new bike. Many might consider that a step backwards. The BB7 is the undisputed best in class when it comes to mechanical disc brakes. Personally, I prefer mechanical over hydro because they are highly adjustable and are easier to service (including on the trail). The main reason I got the BB7 was for the adjustable pad clearance that enables me to widen the pad gap and eliminate rotor rub. The Elixir 3's rubbed no matter what I did, and I tried everything (they do not have pad clearance adjust). The BB7 mated to the speed dial levers is a winning combo. There are surely hydro brakes that have the adjustable features of the BB7, but you are going to pay a lot more money. In other words, the cheaper top of the line mechanical brake is going to perform better than the more expensive middle tier hydro brakes.

It absolutely perfect fit for my mountain bike and excellent product and high quality brake. Thanks

商品の説明ではフロントまたはリヤブレーキ160ローター付きとなっていましたが、F/Rの選択は求められませんでした。 到着した商品は、キャリパー本体は前用・後用のアダプターがそれぞれ付属して2セット入っていましたが、ローターは1枚でした。 ボックス入りのリテール品であればこういうことは無いと思います。本体をプチプチで梱包しただけのバルク品のようでした。 説明書等の書類も全く入っていませんでした。

This is my 3rd set & they have improved overall design since the older grey colored 2006 year model. Still like these brakes for their customization But comparing the price difference Now (2018) with SLX/ XT hydraulic's i'd go with hydraulic. 1 Main advantage of these mechanical brakes is they are easier to install, replace & adjust compared to hydraulic. BB7 have inside/outside adjustment knobs around the rotor & there is a 3rd adjustment on your levers. Quality is better then the other cheaper brands But as of 2018 these are now 30-40% more expensive while hydraulic has become more affordable. After riding 2 sets of XT hydraulic brakes i will no-longer be buying these & glad i still have a new set of bb7 in the box as a backup. Great brake but too pricey now so i had to remove 1 star !!!

Ho acquistato il freno dopo la sostituzione della forcella che aveva gli attacchi solo per freni a disco, ho deciso per questo freno meccanico per spendere meno rispetto ad un freno idraulico. Ho avuto la sorpresa di avere fatto la scelta giusta: frenata potente e molto progressiva non rischio più di bloccare la ruota anche con frenate violente su sterrato come succedeva prima con i v-brake, nonostante la frenata sia più potente. Montaggio e regolazione molto facili seguendo alla lettera le istruzioni allegate anche senza esperienza meccanica! Dopo il montaggio e la regolazione sembrava non frenasse e faceva rumore in frenata, ma dopo un rodaggio in una lunga discesa il freno a cominciato a funzionare a meraviglia e non genera più alcun rumore anche nella frenate più decise.

trés bon frein mécanique, essai ok montage ok........bon produit conforme à la description, excellent frein, bonne modulation à conseiller et à acheter
